The Ipconfig.exe Command Line Tool

Updated: May 24, 2010

Applies To: Windows Server 2008 R2

You use the Ipconfig.exe command line tool to display the current Transmission Control Protocol/Internet Protocol (TCP/IP) configuration. For DirectAccess, you use Ipconfig.exe to determine the Internet Protocol version 6 (IPv6) configuration of a DirectAccess client, server, or intranet node.

The following is an example of the output from the ipconfig command on the DirectAccess client in the DirectAccess test lab (https://go.microsoft.com/fwlink/?Linkid=150613) when it is connected to the Internet subnet.

In this example, the DirectAccess client is using 6to4 to reach the DirectAccess server (the interface named Tunnel adapter 6TO4 Adapter has a 6to4-based IPv6 address and default gateway).

The following is an example of the output from the ipconfig command on the DirectAccess server in the DirectAccess test lab (https://go.microsoft.com/fwlink/?Linkid=150613).

In this example, the DirectAccess server has an ISATAP address (on the interface named Tunnel adapter isatap.corp.contoso.com) and is using 6to4, Teredo, and IP-HTTPS.

You can also use the Ipconfig.exe command line tool to display the contents of the Domain Name System (DNS) Resolver cache with the ipconfig /displaydns command. From the contents of the DNS Resolver cache, you can determine the results of resolving intranet resource names.
